Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a panel-type shutter device for vertically opening and closing an opening of a building by a shutter curtain configured by connecting a plurality of panels in series with a roller chain.

[0002]

[Prior art]

 A conventional panel type shutter device includes a pair of left and right guide rails standing upright on both sides of a shutter opening / closing opening, and a storage box arranged above these guide rails, and lifts between the guide rails. A plurality of upper and lower panel panels to be opened and closed are connected in series on both sides by roller chains (panel connecting chains), and the roller chains are engaged with the panel drive sprockets in the storage box. By the forward and reverse rotation drive operation of the roller chain, the panel is vertically moved in a series posture along the guide rail and horizontally moved in a parallel posture along the storage rail in the storage box. It is designed to be forwarded to. In the panel side-by-side posture, the suspension rollers pivotally supported on the left and right sides of each panel are rotatably supported on the storage rails to suspend and store the panels.

[0003]

[Problems to be solved by the device]

 In such a conventional panel type shutter device, it is difficult to constantly and smoothly perform the panel storing operation from both guide rails to the storage box and the panel extracting operation from the storage box to the guide rails. There is a problem that an extremely complicated panel driving device is required to obtain smooth operation of the panel.

For example, when the shutter-closed panel that is drawn out and deployed between both guide rails is rolled up and stored in the upper storage box, it is connected by a roller chain that meshes with the panel drive sprockets, and both guide rails are connected. The both ends are engaged with each other so as to be able to move up and down, and there is a possibility that the upper and lower panels rising along the guide rail may be folded or clogged during the rising process and the panels may not move. In this case, if it is left as it is, the panel drive sprocket with which the roller chain is meshed is operating, causing a serious accident such as destruction of the panel drive sprocket, roller chain, panel, etc. was there.

In particular, when the shutter is opened, each panel is moved up along the guide rail, and each panel that has moved up is turned from the ascending movement to the horizontal direction along the rotation locus of the panel driving sprocket, and then moves forward. When the panel is transferred to the starting end of the storage rail, the hanging part of the panel connecting chain that connects each panel meshes with the sprocket for driving the panel, and the subsequent panel is pulled downward. Due to the impact load generated, there were problems such as damage to the storage rails, panels falling off, and clogging of the panel connection chain.

A conventional shutter device of this type is disclosed in, for example, the specification of West German Patent Publication No. 270 3512, and in this shutter device, each of a plurality of panels (also referred to as slats) is disclosed. By connecting the lower end of the eye plate member to the left and right end faces with a pin, rotatably supporting the hanging roller on the upper end of the eye plate member, and connecting the roller chain to the roller shaft. However, since the panels are connected in series on both the left and right sides, there is a problem that the connection structure of the panels becomes very complicated.

Further, as described above, the hanging roller pivotally supported on the upper end portion of the eye plate member is inside the roller chain (coupling with the panel driving sprocket) that is connected on the same axis and meshes with the panel driving sprocket. Since it is located between the roller chain), the storage rails must be arranged so that they do not interfere with the roller chain that hangs down when the panel is stored. The space area for hanging the roller chain must be specially secured between them, which complicates the structure and makes the storage box large, which makes it impossible to make a compact storage structure. was there.

The present invention has been made to solve the above-mentioned problems, and it is necessary to specially secure a dedicated space portion for suspending a panel connecting chain that connects panels to each other when the panels are in the parallel position. This allows the storage box to be made smaller and the storage box to have a compact storage structure, and to prevent accidental meshing of the panel drive chain with the panel drive sprocket during the panel transfer operation. An object of the present invention is to provide a panel-type shutter device that can smoothly transfer panels without any trouble during panel transfer.

[0009]

[Means for Solving the Problems]

 In the shutter device according to the present invention, a panel connecting chain, which connects the panels in series, is arranged outside the left and right end surfaces of the panel, and is suspended from both sides of each panel. The roller is arranged further outside than the panel connecting chain, and a side member is provided near the panel driving sprocket. The side member is located below the horizontal line passing through the axis of the panel driving sprocket. The side edge portion on the lower side of the horizontal line prevents the hanging portion of the panel connecting chain from accidentally meshing with the panel driving sprocket.

[0010]

[Action]

 In the shutter device according to the present invention, the suspending rollers are disposed further outside the panel connecting chains which are arranged outside the left and right end surfaces of each panel and which connect the panels to each other. The panel link chain can be hung inside the storage rail that rotatably supports the roller for use, so that the storage rail is attached to both sides of the storage box so that it does not interfere with the hanging of the panel link chain. It can be mounted directly inside. Therefore, in the panel parallel posture area, it is not necessary to specially secure a dedicated space area for suspending the panel connecting chain as in the conventional case, and accordingly, the storage box can be downsized and a compact storage structure can be achieved. it can. Moreover, when the panel is moved, the side edge of the panel drive direction located below the horizontal line passing through the axis of the panel drive sprocket causes unexpected engagement with the panel drive sprocket at the hanging portion of the panel link chain. Since it is blocked, the movement of the panel can be always smoothly performed, and the reliability of the panel shutter device is improved.

[0011]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a pair of left and right guide rails, and these guide rails 1 are composed of vertical guide rails standing upright on both sides of a so-called shutter opening / closing opening such as an entrance / exit of a building or a window.

Reference numeral 2 is a panel having a plurality of upper and lower stages for opening and closing between the guide rails 1, and these panel 2 are panels suitable for a rectangular frame 2a as shown in FIGS. 2 and 4 and 5. The face plate 2b is attached.

As shown in FIG. 3 and FIG. 4, pins (support shafts) 21 projecting outward from both end surfaces of the panel 2 are provided on both upper sides of the panel 2. Is connected to the panel connecting chain 3 composed of the above through a sleeve-like attachment 24 so as to be rotatable and movable in the thrust direction.

In this manner, the plurality of panels 2 that move up and down between the two guide rails 1 are connected to each other by the pins 21 so as to be connected to each other by the panel connecting chains 3 on the outer side of both side end surfaces of each panel 2. It is connected.

A hanging roller 25, which is located further outside the panel connecting chain 3, is rotatably attached to the pin 21 of each panel 2. Further, panel rollers 22 are rotatably supported on both sides of the lower part of each panel 2.

A storage box 5 is arranged above the guide rails 1. The storage box 5 is provided with vertical brackets 5a on both left and right sides, and is located above the guide rails 1 inside the brackets 5a. A pair of left and right panel driving sprockets 8 are pivotally supported, and the panel connecting chain 3 is meshed with these panel driving sprockets 8.

A storage rail 4 is disposed inside the bracket 5 a, and the storage rail 4 is located between the bracket 5 a and the panel drive sprocket 8 above a horizontal line passing through the axis of the panel drive sprocket 8. From the side toward the panel storage direction. In the example shown in the figure, the panel storage direction side is gradually and downwardly inclined to hang down the panel 2 that has passed the panel drive sprocket 8 toward the panel storage direction. The roller 25 is rotatably supported.

The descending end portion of the storage rail 4 is interrupted at a front position separated from the depth end in the storage box 5 by a distance corresponding to the installation space of the opening / closing machine 13, and the descending end of the storage rail 4 is interrupted. A stopper 4a (FIG. 1) is provided at the terminal end portion to prevent the hanging roller 25 rolling on the storage rail 4 from falling off.

In the above, the series of panels 2 are vertically moved in a straight line along the guide rails 1 by the feeding operation of the panel connecting chain 3 by the forward and reverse rotations of the panel driving sprockets 8 and the storage rails 4. It is designed to be continuously transferred along with the lateral movement in a parallel posture. In the parallel posture of the panels 2, the panel connecting chain 3 between the panels 2 hangs down inside the storage rail 4.

In such a panel shutter, an abnormal refraction of the panel connecting chain 3 located near the lower portion of the panel driving sprocket 8 is provided on the side portion near the upper end of the guide rail 1 extending into the storage box 5. A chain slack detecting device 7 for electrically detecting (slack) is provided.

In the vicinity of the panel driving sprocket 8 in the storage box 5, the panel connecting chain 3 is brought into contact with the panel driving sprocket 8 in an appropriate meshing direction or a meshing disengaging direction in the movement process of the panel 2. Chain guide members 9 and 10 for guiding are arranged.

In these chain guide members 9 and 10, the panel guide side chain guide member 9 arranged on the storage rail 4 side in the vicinity of the panel drive sprocket 8 protrudes from the inside of the bracket 5 a of the storage box 5. It wraps around the side of the panel driving sprocket 8 and has a side member 9a and an upper member 9b.

More specifically, the side member 9a of the chain guide member 9 is provided for preventing the hanging portion of the panel connecting chain 3 from engaging with the panel driving sprocket 8, and the panel driving sprocket 8 is provided. the side edge portion 9a ₁ of the panel accommodating direction located a horizontal line downward through the axis of, and a side edge portion 9a ₂ which extends in a horizontal line above the panel receiving direction.

On the other hand, the upper member 9b is an inner member 9c located inside the addendum circle of the panel driving sprocket 8 and a panel connecting chain 3 that is outside the addendum circle and that goes in and out of the storage box 5. And an outer member 9d located in the movement path of the panel connecting chain 3 to contact the panel connecting chain 3 to engage the panel driving sprocket 8 with the engagement direction, the engagement releasing direction and the guide rail 1 direction. It is formed so that it can be contact-guided to. The inner member 9c and the outer member 9d are both positioned above the horizontal line passing through the axis of the panel driving sprocket 8.

On the other hand, the panel inlet / outlet side chain guide member 10 arranged on the guide rail 1 side in the vicinity of the upper end side of the guide rail 1 includes an inner member 10 a located inside the addendum circle of the panel driving sprocket 8. , An outer member 10b located outside the tip circle and in the movement path of the panel connecting chain 3, and comes into contact with the panel connecting chain 3 to disengage the panel connecting chain 3 in the meshing direction. Direction and the guide rail 1 direction, the contact guide is formed.

A panel guide 11 is provided in the vicinity of the panel entrance / exit of the storage box 5 for smoothly guiding the panel rollers 22 at the bottom of each panel 2 in the panel storage direction and the panel feeding direction.

Further, an opening / closing device 13 is arranged in the depth space portion inside the storage box 5. Here, in the storage box 5, the descending end of the storage rail 4 is interrupted at a front position separated from the depth end of the storage box 5 by a distance corresponding to the installation space of the switch 13, so that the storage rail 4 is stopped. The opening / closing device 13 is arranged by utilizing a depth space region in the storage box 5 in which the storage box 5 does not extend.

As shown in FIG. 1, the opening / closing machine 13 integrally has a mounting base 13a, and on the upper and lower portions on both sides of the mounting base 13a, long slots 13b for mounting which are long in the vertical direction are provided. .

Then, in the inner space area of the storage box 5, the opening / closing device 13 is attached to the bracket 5a on one side thereof. At the time of attachment, the opening / closing device 13 is attached to the long hole 13b of the attachment base 13a of the opening / closing device 13. The mounting base 13a is fixed to the bracket 5a by inserting the bolt 28 and screwing and tightening the nut 29 on the bolt 28. Therefore, by loosening the nut 29, the mounting position of the switch 13 can be adjusted in the vertical direction by an amount corresponding to the length of the elongated hole 13b.

The switch 13 has an output sprocket 130 as shown in FIG. 1, and an interlocking sprocket 14 is interlocked with the output sprocket 130 via an interlocking chain 15.

The interlocking sprocket 14 has a first transmission sprocket 17 coaxially and is rotatably attached to the bracket 5 a via a bearing 30. As shown in FIG. 1, the bearing body 30 is fitted and mounted in a notch 5b provided in the bracket 5a so as to be positionally adjustable. Therefore, the rotation shaft connecting the interlocking sprocket 14 and the first transmission sprocket 17 can be adjusted in space between the rotary shaft and the panel driving sprocket 8.

The panel drive sprocket 8 has a second transmission sprocket 18 coaxially, and an endless transmission chain 19 is meshed and wound around the second transmission sprocket 18 and the first transmission sprocket 17. Thus, the rotation output of the switch 13 is transmitted to the sprocket 8 for driving the panel.

Here, the opening / closing device 13, the interlocking sprocket 14 and the first transmission sprocket 17 are substantially the same as the panel 2 at the storage position suspended in the storage rail 4 in the inner space area in the storage box 5. They are arranged in parallel in the vertical direction.

With such an arrangement, the installation space of the switch 13 and the power transmission sprocket (the interlocking sprocket 14 and the first transmission sprocket 17) in the storage box 5 can be minimized. Therefore, it is not necessary to make the installation space particularly large, and the installation space of the storage box 5 is reduced as compared with the case where the switch 13 is externally attached to the storage box 5, and the restriction on the installation work is limited. Can be greatly eased.

A chain tip guide rod 6 parallel to the storage rail 4 is arranged at a position above the storage rail 4 in the storage box 5 so as to be separated therefrom. The chain tip guide rod 6 is arranged by effectively utilizing an upper space between the bracket 5a and both end surfaces of the panel 2 suspended by the storage rail 4.

A free end portion (end side link portion) 3a of a panel connecting chain 3 that meshes with a panel drive sprocket 8 and extends in the panel storage direction is movably moored to the chain tip guide rod 6. There is.

As a result, when the panel 2 is moved up and down, the free end 3a of the panel-linking chain 3 moves along the chain tip guide rod 6, so that it first moves onto the storage rail 4 during the panel storage operation. The length from the pin 21 of the panel 2 to the free end 3a of the panel connecting chain 3 can be shortened.

Therefore, the free end side of the panel connecting chain 3 does not greatly loosen particularly when the panel is housed, and the entanglement of the panel connecting chain 3 during the panel ascending / descending operation can be reliably prevented.

Further, since the free end portion 3a of the panel connecting chain 3 is always moored to the chain tip guide rod 6 as described above, the panel connecting chain 3 is detached from the panel driving sprocket 8 when the panel is extended. Without that, safety and reliability are greatly improved.

Furthermore, as described above, the chain tip guide rod 6 arranged above the storage rail 4 has the panel connecting chain 3 that connects the panels 2 in the parallel posture hung on the storage rail 4 in a U-shape. Since it does not hinder the bending and hanging in a letter shape, there is no need to provide a special space for arranging the chain tip guide rod 6 in the storage box 5, and thus a compact and compact structure can be achieved.

Next, the operation will be described. When the switch 13 is activated in the shutter opening direction, the rotational driving force from the output sprocket 130 via the interlocking chain 15 is the interlocking sprocket 14 → first transmission sprocket 17 → transmission chain 19 → second transmission sprocket 18 → By being transmitted to the panel drive sprocket 8, the panel drive sprocket 8 is rotationally driven in the clockwise direction in FIG.

As a result, the panel 2 between the guide rails 1 is pulled up via the panel connecting chain 3 meshing with the panel driving sprocket 8. When the upper end of the panel 2 reaches the panel drive sprocket 8 due to the pulling up, the upper end of the panel 2 circularly moves along with the panel connecting chain 3 along the pitch circumference of the panel drive sprocket 8 and the storage rail 4 moves. It is guided and moved in the direction.

At this time, the panel roller 22 at the lower portion of the panel 2 is guided obliquely upward by the inclined guide portion 11a of the panel guide 11 and advances in the storage box 5 in the depth direction (panel storage direction).

In this way, the upper end portion of the panel 2 that has moved upward between the guide rails 1 makes an arc along the tooth tip of the panel drive sprocket 8 toward the storage rail 4 (panel storage direction side). At this time, the panel roller 22 is guided obliquely upward by the panel guide 11, so that the panel 2 is maintained in the vertical posture in the lateral shake prevention state when the panel drive sprocket 8 is passed through in the panel storage direction. Moving.

Then, in the panel 2 that has passed through the panel driving sprocket 8 in the panel housing direction, the hanging rollers 25 on both upper sides of the panel 2 move to the housing rail 4. At this time, the suspending roller 25 rolls on the storage rail 4 by its inclination, so that the panel 2 automatically descends along the storage rail 4 in the suspended state in the parallel posture by its descending inclination. Move in.

Then, when the suspension roller 25 of the panel 2 that first migrates onto the storage rail 4 reaches the inclined descending end portion of the storage rail 4, the suspension roller 25 moves to the storage rail 4 at the end. It comes into contact with a stopper 4a provided at the descending end portion and is prevented from falling off from the storage rail 4.

In this way, after the first panel 2 reaches the lower end of the storage rail 4, the subsequent panels 2 are sequentially fed, so that the panels 2 sequentially transferred to the storage rail 4 are adjacent to each other. It is suspended and stored in a hanging state in parallel.

In the above, when the panel 2 is transferred from the vertical movement in the serial posture along the guide rail 1 to the horizontal movement in the parallel posture along the storage rail 4, the sprocket 8 for driving the panel is connected to the chain 3 for linking the panels. Since the panel inlet / outlet side chain guide member 10 extending so as to be able to guide the engagement direction is arranged on the panel inlet / outlet side that first meshes with the panel inlet / outlet side, the panel drive side of the panel inlet / outlet side chain guide member 10 The panel connecting chain includes an inner member 10a located inside the addendum circle of the sprocket 8 and an outer member 10b located outside the addendum circle and within the movement path of the panel connecting chain 3. 3 is surely guided in a predetermined direction with respect to the sprocket 8 for driving the panel.

Even if the panel connecting chain 3 and the panel driving sprocket 8 are abnormally engaged with each other due to some unexpected action, the panel accommodating side chain guide is provided on the panel accommodating side where the meshing ends. Since the upper member 9b of the member 9 is arranged, the upper member 9b has a position inside the tooth tip circle of the panel driving sprocket 8 and above the horizontal line passing through the axis of the panel driving sprocket 8. The inner member 9c and the horizontal line passing through the axis of the panel driving sprocket 8 and located inside the movement path of the panel connecting chain 3 that moves in and out of the storage box 5 outside the addendum circle of the panel driving sprocket 8 Due to the outer member 9d located above, the panel connecting chain 3 is properly engaged with the panel driving sprocket 8 in a proper meshing direction and meshing condition. Contact is guided in the removal direction and the guide rail 1 direction. Therefore, the panel connecting chain 3 is reliably disengaged from the panel driving sprocket 8 and the storage operation of the panel 2 as described above is smoothly performed.

Here, the functions and effects of the inner member 9c and the outer member 9d will be described in more detail. Since the panel connecting chain 3 comes into contact with each other at two portions, the inner member 9c located inside the addendum circle of the panel driving sprocket 8 and the outer member 9d located outside the addendum circle. The contact area is greatly expanded, and the disengagement is performed with certainty and efficiency, and the panel connecting chain 3 and the panel storage side chain guiding member 10 concentrate unreasonable force generated at the time of disengagement. Since it does not occur, unnecessary damage is unlikely to occur and its life is extremely long. In particular, since the contact between the two always occurs at the time of the above reverse activation, such an effect is extremely important.

Further, since the inner member 9c comes into contact with the root portion of the meshing position of the panel connecting chain 3 meshing with the panel driving sprocket 8 and releases the mesh, the mesh releasing effect is extremely high. It is remarkable.

Further, since both the inner member 9c and the outer member 9d are located above the horizontal line passing through the axis of the panel driving sprocket 8, the panel driving sprocket 8 of the panel connecting chain 3 is removed. The disengagement can be performed extremely efficiently and effectively. However, since the inner member 9c and the outer member 9d are located near the starting end of the storage rail 4 when viewed from the side as shown in FIG. 1, it is extremely effective timing for releasing the meshing of the panel connecting chain 3. It can be carried out.

When the above panel is stored, the roller chain 3 moves into the storage box 5 together with the first panel 2 without being entangled by the chain tip guide rod 6, and when the panel 2 is folded and stored, the roller chain 3 is shown in FIG. As shown by the dotted line (a), the panel 2 is regularly hung in a U-shape along the side surface of each panel 2.

In this manner, when each panel 2 changes its direction from the upward vertical movement in the in-line posture along the guide rail 1 to the horizontal movement in the parallel posture along the storage rail 4, the initial horizontal movement in the parallel posture is started. At, the roller chain 3 connecting the preceding panel 2 and the following panel 2 hangs down. In particular, when the panel 2 is conventionally fed to the starting end of the storage rail 4, the hanging portion of the panel connecting chain 3 that connects the panels 2 is entwined with the panel drive sprocket 8 and meshes therewith. The panel 2 was pulled downward, and due to the impact load generated at that time, troubles such as damage to the storage rail 4, dropping of the panel 2 and clogging occurred.

However, in this invention, as shown in FIG. 1, the side member 9a disposed in the vicinity of the panel driving sprocket 8 is a panel storage side located below the horizontal line passing through the axis of the panel driving sprocket 8. Since the side edge portion 9a ₁ of the side member 9a is provided, even if the hanging portion of the panel connecting chain 3 tries to be entangled with the sprocket 8 for driving the panel, the side edge portion 9a ₁ of the side member 9a is surely prevented. For this reason, each panel 2 is reliably and smoothly transferred in the direction of the storage rail 4, the panel 2 is stored, and the shutter is smoothly opened.

The side member 9a is connected to the side edge portion 9a ₁ on the panel housing side located below the horizontal line passing through the axis of the panel driving sprocket 8 and extends above the horizontal line. since even with the side edge portion 9a _2, accidental engagement against sag portion of the panel drive sprocket 8 of the panel interlocking chain 3 can be more reliably prevented. In particular, even if the drooping portion is largely shaken by some action, the unexpected engagement can be reliably prevented. This series of operations is repeated each time the subsequent panel 2 reaches the vicinity of the storage rail 4.

Next, when the opening / closing switch 13 is started in the reverse rotation state from the panel stored state, the rotation output thereof drives the panel drive sprocket 8 to rotate counterclockwise in FIG. 1 to drive the panel drive. The panel 2 on the storage rail 4 is sequentially pulled out in the feeding direction through the roller chain 3 meshing with the sprocket 8 for use.

At this time, in the vicinity of the panel driving sprocket 8, first, the panel connecting chain 3 is moved to a predetermined meshing position of the panel driving sprocket 8 by the side member 9a and the upper member 9b of the panel accommodation side chain guiding member 9. In addition, the side edge portions 9a ₁ and 9a _{2 of the} side member 9a do not cause any unexpected engagement with the panel driving sprocket 8 at the hanging portion of the panel connecting chain 3. Further, the panel connecting chain 3 is smoothly disengaged from the panel driving sprocket 8 by the other panel entrance / exit side chain guiding member 10.

That is, the panel connecting chain 3 is composed of two parts, an inner member 10a located inside the addendum circle of the panel driving sprocket 8 and an outer member 10b located outside the addendum circle. Since they come into contact with each other, the contact area is greatly expanded, and the disengagement is extremely surely and efficiently performed, and the panel connecting chain 3 and the panel inlet / outlet side chain guiding member 10 are forced to exert an unreasonable force at the time of disengagement. Since it is not concentrated in one place, unnecessary damage is unlikely to occur and its life is extremely long. In particular, the contact between the two always occurs at the time of the reverse activation, so such an effect is extremely important.

Further, since the inner member 10a comes into contact with the root portion of the meshing position of the panel connecting chain 3 meshing with the panel driving sprocket 8 to release the mesh, the mesh releasing effect is extremely remarkable. is there.

In the process of raising and lowering the panel 2 as described above, if the panels 2 are folded or clogged in the guide rail 1 by any chance, the panel 2 will not move and will be left unattended. It causes a big accident.

However, in this case, since abnormal refraction occurs in the panel connecting chain 3, the chain slack detecting device 7 detects the abnormal refraction, which causes a large amount of folding or clogging between the panels 2. It can respond immediately to scandals such as accidents.

Therefore, the storage rail is stored so as not to interfere with the hanging of the panel connecting chain. It can be installed directly inside the brackets on both sides of the box, so that in the panel parallel posture area, it is not necessary to separately secure a dedicated space area for hanging the roller chain as in the conventional case, and Therefore, there is an effect that the storage box can be downsized and the storage structure can be made compact.

Moreover, a side member is disposed in the vicinity of the panel driving sprocket, and the side member has a side edge portion on the panel storage direction side located below the horizontal line passing through the axis of the panel driving sprocket.
